STAND-PIPE FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 675,889, dated June 11,1901.

Application filed August 8,1900. Serial No- 26,2Q5. N0 model.)

To all whom, it may concern:

Be it known that I, CHARLES GULLAND, a citizen of the United States,residing at littsburg, Pennsylvania, have invented certain new anduseful Improvements in Stand-Pipes for Locomotives, of which thefollowing is a specification.

My invention relates to a stand-pipe for locomotive use, and is designedto produce a simple construction in connection with a valve of theGulland type as disclosed in Letters Patent No. (355,342, dated August7,1900, the improvement being devoted to the details of constructionwhereby I secure ease of movement in the turning or swiveling action ofthe stand-pipe and provide for repairs or replacement of the parts whenworn or injured without requiring the dismantling or taking apart of thestructure.

I have illustrated the invention in the accompanying drawings, whichshow, in-

Figure 1, the upper part of the stand-pipe in elevation, with the lowerpart, including the valve, in section. Fig. 2 shows simply the lowerpart in elevation to illustrate some of the details. Fig. 3 is adetailed sectional view of a part of the cage and its support.

The stand-pipe proper is shown at A and extends down through a pedestal1;, which aids in its support and keeps it steady, the upper end of thepedestal being covered by a flange a, secured to or forming a part ofthe pipe A. The pipe A turns in the pedestal, and at its lower end it isfitted to the recessed end of an elbow O, the open end of whichconstitutes a stufling-box to make the joint water-tight. The lower endof the stand-pipe turns in the recessed end of the elbow C, but does notrest upon the bottom of the recess, being held away from the bottom by asupporting-cage D, which is made preferably in halves bolted together,as shown in Fig. 2. This cage has an upper ring and a lower ring 2 31,connected by integral struts or braces 4, and is interposed between aflaring projection (1, extending out from the periphery of thestand-pipe a short distance above its lower end, and a projecting flangee, extending out from the upper end of the elbow O. Resting upon theflange e is a two-part ring f, grooved to receive a series of rollers g,and resting upon these rollers is the lower ring 3 of the cage,which isalso channeled or grooved to correspond with the ehannel orgroove of thering f. It will thus be seen that the stand-pipe is supported throughthe cage D upon a series of rollers,and this provides for a very easymovement in the swiveling action of the stand-pipe as itis turned intoand out of line with the tender of the locomotive. The grooves in theringsfand 3 are, as shown, sufficiently shallow to provide a spacebetween the rings, and through the opening oil may be freely supplied tothe balls and their condition may be readily observed at all times. Bymaking the cage and the ringf in halves or sections they may be detachedand removed for repairs withoutdismantling the apparatus. In order tofacilitate the removal of the parts, I have provided the flange (l withproject ing lugs, and when it is desired to take out the cage I jack upthe stand-pipe A through these lugs, and thus support the pipe while theparts are being repaired or replaced. The valve, which is of the Gullandtype, is shown at E, and the auxiliary valve I which controls theoperation, is acted upon by the end of a lever 71, pivoted at i on thecasing of the valve. The end of this lever is bent into ring or circularform and is made of two parts bolted together encircling the lower endof the stand-pipe. In order to operate the valve, the circular end ofthe lever 7!. must be raised, and this movement is effected through thebent end 7.: of a rod l, which moves in guides secured to thestand-pipe, and this rod is connected by a rod m to a horizontal rod nto a bell-crank and a spring 1) to a lever 1 pivoted at the dischargeend of the stand-pipe, so that by drawing upon this lever the rod in israised, lifting the bent end 70, which engages the encircling orring-shaped end of the lever h, thus opening the auxiliary valve andallowing the main valve to operate. lly encircling the stand-pipe withthe end of the lever h the end will engage the ring whatever itsposition.

In order to drain the stand-pipe, the elbow is provided with a channel1, to which is fitted a discharge-valve, which may lead to a suitabledrain. The end of the stand-pipe has an opening .9 therein alining withthe opening 1*, and this allows the stand-pipe to be drained in certainpositions; but when moved ICO to close the opening to the passage I thedraining action ceases.

\Vhat I claim is 1. A stand-pipe comprising a pipe A, a cage supportingthe same and antifriction-bearings supporting the cage, said cage beingmade sectional and adapted to be removed.

2. A stand-pipe com prisinga pipe A, a cage supporting the end thereofand having a grooved lower ring and a lower bearing-ring also groovedand adapted to contain a series of balls, the grooves being shallowerthan the diameter of the balls so as to leave a space between the cageand the lower ring for lubricating purposes, substantially as described.

3. A stand-pipe comprising a verticallymovabie pipe A, a sectional cagesupporting the same, said cage being removable, substantially asdescribed.

4. A stand-pipe comprising a pipe A, an elbow adapted to receive the endof the pipe, a ring supported by said elbow and grooved to receiveantifriction-bearings, and a cage interposed between said bearings andsaid stand-pipe for supporting the latter, substantially as described.

5. In a stand-pipe, a pipe A, a flange pro jecting from the lower endthereof and a sectional cage surrounding the lower end of the said pipeand serving to support the same through the said flange, substantiallyas described.

6. A stand-pipe comprising a pipe A, a cage independent of thestand-pipe and adapted to support the same and lugs projecting from thestand-pipe and adapted to be utilized to support the same when the partsare required to be renewed or replaced, substantially as described.

7. In a stand-pipe, a valve, a lever for operating the valve having anend encircling the stand-pipe and a rod having a bent end adapted toengage the encircling part of the lever to operate the same and meansfor giving movement to the rod, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
